Sticky multiplier wilds are one of the best features you can have in a cluster slot. They stay on the grid after every cascade, move to a new random position, and increase their multiplier by +1 each time they're part of a winning cluster. This creates a snowball effect – one lucky spin can keep going for ages as the wilds build to 10x, 20x or higher while new symbols drop in. The longer the chain, the crazier the payouts get. High volatility, but that's where the fun is. I always start with the demo to watch the multipliers grow without risk. This site
